Abstract:Abstract:Ploughed-on terraces in loess landscape of strongly developed high plains. The ploughed-on terraces were one of the techniques for agricultural use of steep slopes in loess landscapes of developed high plains, the example of which is described fragment of the valley in Bartłomiejowice near Nałęczów. Giving up the agricultural use makes disappearance of those anthropogenic-erosion relief forms in the landscape structure. The authors postulate to protect -by restoring the meadow-pasture use -the charact… Show more
“…Most lynchets studied in Ethiopia are very similar to those in NW Europe, where it has also been shown that they resulted from soil translocation by tillage and water erosion of temporarily bare soils (Bollinne, 1971;Gerlach, 1963;Ozer, 1969;Patro et al, 2008;Poesen et al, 1997;Van Oost and Govers, 1998). This study did not consider risers of non-agricultural origins such as brick earth excavations, river terraces, and road or river banks.…”

“…As observed in Ethiopia, tillage erosion by simple tools, in addition to sediment transport due to water erosion, can lead to fast soil accumulation in the lynchets (Chartin et al, 2011;De Alba et al, 2004). As the rate of tillage erosion is independent from slope length, imposing lynchets can also develop on narrow parcels, established along the contour, as shown elsewhere (Patro et al, 2008).…”

This paper investigates soil stratigraphy of lynchets in sloping lands in eastern Belgium, and rates of their development by comparison to tillage translocation by non-mechanised agriculture. In Belgium, detailed topographical surveys and augerings were carried out at three sites that were under cropland till 1900-1950. Rates and diffusion constants of current non-mechanised tillage erosion were monitored in Ethiopia using tracers, and by precise Key words: Plough; Cultivation terrace; Ethiopia; Lynchet; Tillage erosion Nyssen, J., Debever, M., Poesen, J., Deckers, J., 2014.

Section: Abstract: Determining the Spacing Of Ridge Terraces On Arablmentioning
The practice of many countries has shown that terraces can significantly prevent land degradation processes such as excessive soil erosion, landslides. Condition is good layout, proper construction, and then proper maintenance. Practical application in many countries showed that terraces can significantly prevent processes leading to the degradation of land, such as the excessive erosion of soils and landslides. The requirement for this is well-planned, adequate construction, and later – proper conservation. In Poland this is a little popular method. In the article, the dorsal spacing terraces were calculated for two catchments – in the central and south-western parts of Poland. Meteorological and soil data were used for Puczniew station (Ner catchment) and Boleścin station (Mielnica catchment). Kolmogorov–Smirnov test was performed to assess the compatibility of a given feature with a normal distribution, then the distribution of the probability distribution was developed. For probability 1, 50 and 90% the spacing of terraces was calculated using Ramser and Morgan method. The results obtained were combined with the results from the USLE model. Hydraulic methods have shown greater spacing for the Mielnica catchment (loess soils) compared to the Ner basin (clay loam). For the USLE model, the larger spacing was calculated for the Ner basin. From the practical application to the acceptance of land user will be the maximum distance calculated by different methods. The highest terrace spacing values were obtained using the Morgan method for the Mielnica catchment, for the Ner catchment model USLE.
“…Apart from their functions in material redistribution, they provide important biological corridors and places of increased biodiversity in tilled land, and they retain the surplus run‐off increasing the amount of water retained in the watershed and, last but not least, represent a key landscape component resulting from long‐term agricultural management. A common occurrence of lynchets in the agricultural landscape, both historical and present, has been described worldwide: in France (Chartin et al ., ; Froehlicher et al ., ), Belgium (Nyssen et al ., ), Poland (Patro et al ., ), Germany (Moldenhauer et al ., ; Stolz, ; Larsen et al ., ), Spain (Poesen et al ., ), North America (Vieira & Dabney, ), South America (Dercon et al ., ) and Africa (Lewis, ; Nyssen et al ., ), most often in undulating dynamic landscapes with a prevalence of small farms. In Great Britain (Favis‐Mortlock et al ., ) and Denmark (Nielsen & Dalsgaard, ), prehistoric lynchets have been studied related to Celtic settlements.…”
Lynchets represent a traditional landscape element in agricultural landscapes having multiple functions in soil material redistribution, water retention, biodiversity and landscape character. They act as a barrier to translocated soil matter, and they can store a significant amount of soil material and soil organic carbon. Lynchets developed in many regions during formation of agriculture landscape as field boundaries or path networks. Further management led to unleveling of the fields and development of lynchets. During the 20th century, a large number of lynchets disappeared in Central and Western Europe due to land consolidation, intensification and industrialization of agriculture. This study was performed at a large agricultural study plot with dissected relief (Central Czechia) with the aim of assessing the influence of former but now completely levelled lynchets on actual soil stratigraphy, depth, soil organic carbon stocks and structure of soil units. The soil profiles in 20-m-long transects perpendicular to former lynchets were analysed, and statistical relationships between the positions above, in and below the former lynchets were assessed. The results showed high variability of studied soil characteristics in the areas of former lynchets. Statistically significant greater A horizon thickness (50-100 cm) and SOC stock (12.7 kg/m 2 ) were observed in the location of a former lynchet, where colluvial soils were identified. Other areas of accumulation were identified below a lynchet, at the former break-in-slope. The strip above a lynchet was identified as a sediment delivery area, having a partly truncated soil profile. SOC concentration and SOC stock in A horizon did not differ significantly in the positions in, above or below a lynchet.
